iPhone Life - Best Apps, Top Tips, Great Gear

This article is highly recommended for programmers and people interested in shooting video.

As of iOS 7 beta 2, the built-in Camera application can't make use of the extra pixels of the sensor when zooming. Only custom-written, third-party apps currently can do that. Hopefully Apple fixes Camera in the final version of iOS 7; before that, should you want to use zooming while shooting video, avoid using the Camera app and make sure you write or install an iOS 7-specific video recorder application for best results.

Many of my readers have asked for a complete elaboration on the brand new zooming features of iOS 7, both in the stock Camera application and the programmatic API support (AVCaptureDevice.videoZoomFactor and the related, highly useful properties AVCaptureDevice.activeFormat.videoZoomFactorUpscaleThreshold and AVCaptureDevice.activeFormat.videoMaxZoomFactor).

Ever since the social app Snapchat debuted on the App Store two years ago, parents everywhere have been hyper aware of the downsides of their teens downloading and using the popular app.

Parents are concerned about enabling their children to receive (or send) sexually inappropriate photos or videos, photos that bully, or images taken in bad taste. If parents think they can routinely check their teen's phone to look for signs of these behaviors, Snapchat puts an end to that. When you take a photo in the app, it's not saved to the camera roll, and when you view a photo in Snapchat, it's available to the viewer for less than 10 seconds, and then it's gone forever.
